BLACKING-MACHINE.

Specification of Letters Patent.

Patented June 25, 1918.

Application filed April 14, 1917. Serial No. 162,819.

To all whom it may concern.-

Be it known that I, JOHN W. AULsoN, a citizen of the United States ofAmerica, and a resident of Lynn, in the county of Essex and Commonwealthof Massachusetts, have invented certain new and useful Improvements inBlacking-Machines, of which the following is a specification.

This invention relates to machines for applying blacking or coloringmatter to the face of a hide in order to give it a required finish, andit has for its object the provision of means whereby better work may beaecomplished and the adjustments of the feed roll and the variousoperating brushes may be quickly made to bring these devices into properposition relatively to each other.

The invention consists in certain novel features of construction andarrangement of 2o parts which will be fully understood by reference tothe description of the drawings and to the claims hereinafter given.

For the purpose of illustrating the invention one preferred form thereofis illustrated in the drawings, this form having been found to givesatisfactory and reliable resuits, although it is to be understood thatthe various instrumentalities of which the invention consists can bevariously arranged and organized, and that the invention is not limitedto the precise arrangement and organization of these instrumentalitiesas herein shown and described.

Of the drawings:

Figure 1 represents an end elevation of a machine embodying theprinciples of the present invention.

Fig. 2 represents a vert-ical section of the same.

Fig. 3 represents an elevation of the saddle and adjustable supportcarrying the bearings for the feed roll shaft and the shafts of thevarious brushes.

Fig. 4 represents a plan of the saddle.

Fig. 5 represents a plan of the adjustable bearing supporting member,and

Fig. 6 represents a section on line 6-6 on Fig. 3.

Similar characters designate like parts 50 throughout the severalfigures of the` drawn the drawings, 1() is the frame of a machine havingrevolubly mounted in bearings thereon a shaft 11 having a bed roll 12mounted thereon and revoluble therewith. An inclined table 13 isprovided over which the hide is fed between the pan 14 and said bed roll12 until it is engaged by the revoluble blacking brush 15 which retainsthe hide on said bed roll and causes it to be fed in contact with thebed roll 12 beneath the distributing brush 16 and finishing brush 17.The pan 14 is partially filled with the liquid material to be used uponthe hides. This material may be blacking or any desired coloring matter.

Partly submerged in the pan 14 is a feed roll 18 which deposits aportion of the liquid material upon the brush 15 from which saidmaterial is deposited upon the surface of the hide on the bed roll 12.The material thus disposed upon the hide is distributed over the entiresurface of the hide by the distributing brush 16, and as said hidepasses beneath the brush 17 the surface of the hide is finished, thematerial being more evenly spread over the surface and polished by thelatter brush.

The bed roll 12 revolves in the direction of the arrow a on Fig. 2 ofthe drawings and all surplus liquid which may be disposed thereon isremoved therefrom by means of the scraper 19, which may be of anywellknown construction. The frame 10 has revolubly mounted therein adriving shaft 20 to which rotary movement is imparted by a pulley 21 andbelt 22. On the shaft 20 is a pinion 23 meshing with an intermediatepinion 24 which in turn meshes with the teeth of a gear 25 secured tothe shaft 11, and to which rotary movement is imparted by the train ofgears 23, 24, and 25.

Loosely mounted on the shaft 11 is an arm 26 having an operating handle27 by which said arm may be moved about the axis of the shaft 11 andclamped in adjusted position by means of the clamping member 28 coactingwith the slotted arc 29 secured to the frame 10 at 30.

The shaft 31 of the feed roll 18 has secured thereto the gear 32 meshingwith the pinion 33 on a stud 34 carried by the arm 26, said pinion 34having secured thereto a gear 35 driven by the gear 25 on the shaft 11.

Secured to each end of the frame 10 is a saddle 36, to one end of whichis adjustably secured the bearing 37 for the shaft 31 of the feed roll18. The rear end of the saddle 36 has adj ustably mounted thereon thebearing 38 for the shaft 39 of the finishing brush 17.

By means of this construction the bed roll 18 and finishing brush 17 maybe adjusted horizontally toward and from the bed roll 12 andthe bearings37-39 for the shafts 31, 39 then clamped in adjusted. position by meansof the nuts 4041 respectively.

The saddle 36 has projecting upwardly therefrom an arm 42 which isslightly inclined toward the rear and is provided with a slot 43extending longitudinally thereof. Movable lengthwise of the arm 42 is across member 44 having a transverse slot 45 lin which the arm 42 ispositioned with its edges in contact with the side walls of said slot 45as shown in Fig. 6.

A bolt 46 extends through the slot 43 of the arm 42 and also through thecross member 44, the outer threaded end of which is provided with aclamping nut 47 by which the member 44 is prevented from being displacedrelatively to the arm 42.

The member 44 is provided with an ear 48 having a threaded opening 49therethrough in which is mounted the threaded shank 50 of the adjustingmember 51 having a head 52 provided with holes to receive a spaniierwrench when it is desired to adjust the height of the member 44relatively to said arm 42.

The lower end of the member 51 has a reduced end 53 freely revoluble inan ear 54 on the saddle 36 and' prevented from end movement by thenut55. The member 44 is provided with a rearward projection 56 having ahole therein in which is positioned the threaded shank 57 of a bearing58 for the shaft 59 of the distributing brush 16.

The bearing 58 may be raised and lowered inthe hole in said projection56 and then locked in adjusted position by the nuts 60 on said threadedshank 57. The member 44 is also provided with a forward projection 61having a radial slot 62 through which extends the threaded shank 63 of abearing 64 for the shaft 65 of the brush 15, said shank be ing providedwith a clamping nut 630.

The bearing 64 is provided with a rib 66 which is positioned between theside rails 67 on the upper face of said forward projection 61. It isobvious that by means of this construction the brushes 15 and 16 may beadjusted vertically simultaneously while the brush 16 may beindependently adjusted vertically for fine adjustment and the brush 15may be adjusted horizontally toward and from the brush 16. In likemanner, means is herein provided whereby the feed roll 18 may beadjusted horizontally toward and from the brush 15 with which it coacts.

The finishing brush is adapted to be moved horizontally so that it willassume the proper position relatively to the bed roll 12 and then theother adjustments may be quickly made to bring the brushes 15 and 16 andthe feed roll 18 into proper position relatively to each other and alsoto the bed roll 12. y

It is believed that the operation and many advantages of the inventionwill be fully understood from the foregoing description.
